Gas control set

From 201.00 (EUR)


  • Regulate oxygen or CO2/pH levels in water
  • Solenoid valve for gas flow
  • Ceramic air stone for effective gas exchange


This accessory set is used for regulation of dissolved gasses (oxygen, nitrogen, and CO2) levels in water. The solenoid valve can handle up to 8 bar and can be switched on/off using our PowerX4 Bluetooth/ethernet power strip. When activated, the solenoid valve opens and gas from a pressure bottle will flow through the tubing and out of the air stone as fine bubbles.

Solenoid valve with push-in fittings

From 180.00 (EUR)


  • The solenoid valve can deal with up to 8 bar on the working side (A).
  • The push-in fitting have an orifice of 2 mm with a G1/8 port connection.


The miniature solenoid valve is used for shut-off, dosing, filling, ventilating and for technical vacuum. It is of modular design and may be mounted individually or as a block on a multiple manifold.

Fiber cable

From 66.75 (EUR)

A polymer optical fiber is needed as a light guide between the fiber optic instrument and the sensor spots.

Fiber cable fixture

40.25 (EUR)

Fixture to attach a polymer optical fiber cable to a planar surface.

Maintenance kit for MINI-DO

100.00 (EUR)


  • Maintenance kit with spare parts for the MINI-DO oxygen probe


This maintenance kit includes 10 spare membranes, a membrane cap, polishing pad, and 50 ml Type-2 electrolyte fluid.

MINI-DO O2 probe membrane tool

80.00 (EUR)


  • Tool for replacing the membrane in the MINI-DO probes


Easy-to-use tool for replacing the membrane in the MINI-DO oxygen probes. Membranes are part of the optional Maintenance kit for MINI-DO.

Silicone glue for sensor spots

30.00 (EUR)


  • One-component adhesive/sealant
  • Easy to apply
  • Cures (to a tough, flexible rubber) at room temperature when exposed to moisture in the air
  • Good adhesion to many substrates
  • Acetoxy cure system
  • Stable and flexible from -60 ºC to +180 ºC (-76 ºF to +356 ºF), with short peaks up to +205 ºC (401 ºF)
  • Excellent dielectric properties
  • Complies with MIL-A-46106
  • Complies with FDA 177.2600


We offer this clear and non-toxic silicone adhesive for mounting sensors spots on many substrates such as glass and most common engineering plastics. Suitable solvents include isopropyl alcohol, acetone or methyl ethyl ketone.

On exposure to moisture, the freshly applied material will "skinover" in ~7 min. Any tooling should be completed before this skin forms. After skin formation, cure continues inward from the surface. In 24 hours (at room temperature and 50 % relative humidity) the silicone glue will cure to a depth of about 3 mm.
